LUBRICATING-PAD FRAME.

Patented Aug. 14, 1906.

Original application filed October 18, 1905, Serial No. 283,248. Divided and this application filedMarch 15,1906- Serial No. 306,197.

To all whom it may concern:

Be it known that I, GOTTFRIED MAASS, a citizen of the German Empire, residing at Duisburg, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Lubricating-Pad Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This present application is a divisional one and a part of the application, Serial No. 283,243, filed October 18, 1905, for lubricating-pad frames for axles of railway-cars.

This invention relates to a construction of lubricating-pad frames for axle-boxes of railway-cars and the like whereby the lubricating-pad and its supp0rttl1at is to say, the late to which it is directly secured-can fol- C ow the longitudinal movements of the axle, so that any damage to the rounded-off portions of the axle by cutting action of the edges of the lubricating-pad carrier is avoided.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the lubricating-pad frame. Fig. 2 is a front elevation of the lubricating-pad frame. Fi 3 is a longitudinal section through the lubricating-pad frame, and Fig. 4 a plan of the frame.

In all the figures the lubricating-pad itself has been omitted, and in Fig. 1 the axle-journal is indicated by dotted lines.

17 18 represent the lubricating-pad carrierthat is to say, a plate made in this case, for instance, in two parts and curved to conform to the axle journal. This plate is mounted on a rod 27, which in its turn is suported by two triangular brackets or frames.

hese frames consist each of two arms 23, rotatably mounted on a late 3 about rods 24.25 in such manner that t e rods 24 25 form pivots for the parts of the two frames. In order that the frames may be movable, the holes through which the spindle 27 is passed are made as longitudinal slots 26, so that it is possible to fold the bars 23 completely down to the plate 3that is to say, to press down the triangle into a straight line. Moreover, as shown in Fig. 3, it is possible to bring the rod 27 either nearer to the rod 24 than to the rod 25, or vice versathat is to say, to shift it in the direction of the carriage-axle.

About the rods 24 25 are arranged springs 29, pressing with their ends 30 against the plate 3, resting on the bottom of the axleboxes, the ends 31 engaging with the frame parts 23. The springs in question have the tendency to increase the angle between the frame parts 23 and the bottom plate 3that is to say, have the tendency to raise the rod 27 and with it the pad-carrier. The padcarrier is therefore supportedin such manner that it can be easily moved to a considerable extent in longitudinal direction and yet remain pressed hard against the axle-journal. A shifting of the triangle apex 27 is of course possible only when the lubricating-pad frame is slightly depressed from the top downward. In that state it is, however, always in the axle-box in order to exercise pressure against the axle-journal.

The bracket 33 serves as a handle for introducing the pad-frame into the closed axlebox, and the possibility of folding of the parts 17 18 of the lubricating-pad carrier (indicated in Fig. 3) serves also to facilitate the introduction into the axle-boxes. This does not, however, form the object of this invention.

What I claim is 1. In a lubricating-pad frame, the combination, with a pad-carrier, and a cross-rod supporting it of a base-plate, and springpressed arms pivoted to the said base-plate and operatively connected with the said cross-rod.

2. In a lubricating-pad frame, the combination, with a ad-carrier, and a cross-rod supporting it; of a base-plate, hinge-pins carried by the said base-plate, arms pivoted to the said hinge-pins and operatively connected with the said cross-rod, and springs wound about the said hinge-pins and pressing the said arms upward.

In testimony whereof I aflix my signature in presence of two witnesses.
